Alfa Laval CARBOBLEND™Blending and carbonation

Introduction

The CARBOBLEND™ process module is designed forblending two or more liquids, with subsequent carbonation.

Application

Blending and carbonation of beer, soft drinks and otherbeverages.

Benefits

• Compact design• Outstanding blending accuracy• Efficient dissolving of CO2• Versatile and adaptable to different process requirements• Low maintenance.

Design

The CARBOBLEND unit is self-contained and factory pre-assembled on a frame. In compliance with food industryregulations, all components in contact with the process liquidsare made of stainless steel with heat resistant seals. It isdesigned for CIP.

Working principles

Blending: Blending is carried out by continuously controllingthe ratio of flows of the constituent liquids, e.g. beer andwater. The blending ratio is preselected on the control panel.The microprocessor receives continuous data from the flowmeters in the beer and water / beer lines and regulates thecontrol valve in the water / beer line, so that the presetblending ratio is accurately maintained. Alternatively, theoperator keys in the known and required properties, such asalcohol content or original gravity of the feed and of the endproducts. The corresponding blending ratio is thenautomatically calculated and used instead.

Carbonation: CO2 is injected in the product line directly,

without utilising any porous disc or sinter candle. This meansthat CIP of the CO2 and product lines can be carried out

without reduction of flow.

A specially designed mixer / accelerator makes sure that theCO2 dissolves rapidly into the product by a combination of

turbulent flow and increased pressure.

An analyzer is included after the mixer and carbonatedproduct is analyzed for CO2 content.

A control valve regulates the CO2 flow to keep a constant CO2content in the product. A PLC controls the plant operation.

Relevant process data displayed:• Actual and setpoint blending ratios• Actual and setpoint flow rates• Actual and setpoint CO2 content

• Accumulated production volume• Plant status• Controller settings• Alarm status.

A fail-safe system is monitoring the operation.

Options

• In-line analyzer. CARBOBLEND can be equipped with ananalyzer for continuous in-line adjustment of the alcoholcontent and / or original gravity of the beer after blending.A Brix meter can be supplied for control of syrup contentin soft drinks and other beverages.

• Remote control• Communication with other control systems.
